What we found

5 battery models are matched as running it across 2 brands, by setting each maker's published figures against the other — neither names the pairing.
12 V deep cycle marine batteries.
Sonar must not run off the trolling motor battery.
Published as 12 V · 52 A · 54 lb.
20 specifications are published for it, each with the source it was read from.

Assembled from the evidence on this page. Every figure and count below is shown with the source it was read from.

At a glance

System voltage 12 VPeak draw 52 A54 LB thrust

That is a peak, not a continuous rating. The maker publishes no continuous draw for this — see below for what they say about it — so a pack sized on the figure above is sized for the worst moment rather than for the load it will hold.

The maker’s own installation requirements: 50-amp (good) or 60-amp (best) manual reset circuit breaker, 10-gauge included, not extended beyond 1.8 m (6 ft); 8-gauge beyond that. A battery that meets the draw does not make the wiring optional.

Note that 52 A is higher than the smallest breaker the maker names above (50 A). That is our arithmetic from their own two figures, not a statement about which breaker to fit — read the manual for your own motor before choosing one.

Batteries documented to run this

The figures below line up. Neither manufacturer states that this pack runs this device — that is our reading of what each of them published separately, not a claim by either of them or a test by us. Even where every stated figure agrees, these can still decide it:

A motor’s published draw is usually a peak, not the load it holds — the two numbers are not the same kind of quantity
A maker’s amp-hour minimum and their reserve-capacity minimum can give different answers about the same battery
Conditions attached to the chemistry, such as a speed limit for running on lithium
Whether the pack may be wired in series at all, where the device needs 24 or 36 volts
The charger, which both makers put conditions on and neither supplies
Case size, hold-down and terminal type — fitting the space is not being secured in it

Worth confirming with the manufacturer or a dealer before buying.
